More than 15,000 Sanders supporters gathered for the rally, just two days ahead of the March 3 California primary election.

“I’m here to ask for your support to win on Tuesday,” Sanders said. “Let’s defeat Trump.”

The event, which was open to the public, included appearances from Dick Van Dyke and comedian Sarah Silverman.

As people arrived to the rally, CBSLA spoke to Sanders supporters about the reason they’re backing the candidate.

“My primary reason is climate and the environment,” said Sanders supporter Laura Nava. “In comparison to other candidates, Bernie Sanders has a really long record of voting well when it comes to the environment. I think that’s something that impacts all communities across both party lines.”

The rally is one of two stops in Southern California for Sanders Sunday. He also held a rally this afternoon in San Jose. Sanders’ campaign has focused on turning out the vote in California, which is participating in the delegate-rich Super Tuesday on March 3 when more than a dozen states will host primary elections.

It appears his supporters are hearing the message.

“Show up to vote in numbers,” said rally attendee Daniel Navar. “We have to show up and vote, and we have to vote this current president out.”

Some are still weighing their options, but are making their desires clear: they want passion and change.

“I’m looking for someone who is willing to reimagine what the presidency can and should look like,” said undecided voter Sharonda Bossier. “I’m looking for someone who is able to mobilize and energize the base.”

In front of the crowd, Sanders said he would use an executive order to legalize marijuana nationwide.

He also addressed criticisms that he didn’t vote for tighter gun restrictions in the past.

“We will do what the American people want,” Sanders said. “And that is end the sale and distribution of assault weapons in this country.”

Sanders is expected to speak in Salt Lake City, Utah on Monday. He’ll also make another appearance in Minneapolis.
